DARTMOUTH — University of Massachusetts Dartmouth’s 114th commencement ceremonies will be spread over four days for the first time, mainly to accommodate more visitors and any changes due to the weather.

“What we are trying to do is accommodate as many people in as comfortable a space as is possible,” said university spokesman John Hoey.

Last year, the university had two ceremonies — one for graduates on Saturday and one for undergraduates on Sunday. The Sunday ceremony was delayed due to rain and moved under a 5,600-seat tent.
